Reconstruction of vector field from spherical harmonic coefficients

  1. Oct 26, 2008 #1
    The JGM3 model of earth's gravity is expressed in the form of coefficients C and S to Legendre polynomials in r, theta and phi which give the gravitational potential

    U = [tex]\sum[/tex][tex]\sum[/tex] CV + SW

    Can anyone tell me the algorithm for calculating acceleration vector g(r, theta, phi) from the coefficients, i.e. [tex]\Delta[/tex].U expressed as a polar vector?
